when trying to install software with the NSIS installer. If the NSIS cannot install something, the error
which occurs could be due to several reasons. For example, improper configuration settings, corrupted installation files, firewalls, viruses, etc. It could also be a NSIS installer issue
where the source program to be installed does not have a complete control over the software. Running Scandisk, renaming the software to be installed or running a scan with an antivirus program are just some of the ways to fix the problem. The NSIS cannot install software error
